Having thus fully described my invention, wl at I claim as new, and desire to secure by Letters latent, is-

il. ln a breakdown gun, the combination with a frame and a barrel, pivoted hammer, an eXtrac-torbar having a recess, acockinglever pivot-ed to the frame `at the rear and above the hammer-pivot and provided with a forward and upward extension projecting into said recess for engaging and moving the extractor in reverse directionsga cooking member carried by the barrel and engaged with the upper and rear faces of said extension, and a shoulder on the lever engaging the hammer iu front of its pivot for cooking the hammer.

2. ln a `breakdown gun, the combination with a frame and a barrel, of a pivoted hammer having a 'lorwidly-projecting arm, an extractor-bar, a cooking member carried by the barrel, a cooking-lever pivotcd at its rear end 'to the frame at one side ol' the hammer-A pivot, and extending forwardly beneath and in front oi' thc eocking member and engaged with said member, the iront endA of said lever being extended upwardly and engaged with the extraetordiar to move the same in reverse directions as the gnn is opened and closed, and a shoulder on the lever engaged with the lower iaee of the arm oi' theliammer forcocking the hammer.

S. ln a brecch-lomling gun,the combination with a trame and barrel, ol' a pivoted hammer having a forwardly-projecting arm, an cxtractor-bar having a recess, a cocliing member on the barrel, anda cooking-lever havingone end iulcruined on the frame at the rear of the .breecheface and its other end engaged with said member and projecting into the recess, tor sininltaneonsly moving the extractor-bar endwise and rocking the lever as the gun is opened and closed, the intermediate portion "i the lever having means to engage said arm and cock the hammer as the gun is opened.

Li. ln a breakdown gun, the combination with a frame and barrel, of a pivoted hammer having a forwardly-projecting arm, an eX- tractor-bar, a spring-actuated ejector-hammer engaged with the end face of the extractorbar, aidetent 'for the ejector-hammer," means actuated by the iiring of the main hammer to trip the detent when the gun is opened, a cockingdever pivoted at its rear end to the frame and having a hook-shaped forward end engag- ICO
